Abstract:
EPA's proposed rule sets emission limits for lead compounds released from primary lead smelters. Lead compounds are used as a surrogate for all metallic hazardous air pollutants being emitted from these facilities. Control devices that are used to reduce emissions of lead compounds will also remove other metallic hazardous air pollutants with essentially the same efficiency. Therefore, in controlling emissions of lead compounds, facilities can also control emissions of other metallic hazardous air pollutants.
